Elastic connection terminal

Abstract

Elastic connection terminal for an electric switch or junction device, comprising an elastic loop placed on a conducting part and an auxiliary part capable of forming a stop for the end of the cable. The assembly and behaviour of the terminal are improved by placing an auxiliary part 30 in contact with the back of the support strip 18 of the conducting part 14 . The part 30 is provided with at least on attachment element, for example a lug 34 , engaged with the connection region of the support strip, and guide panels for the cable. The guide panels extend close to the connection area and they have a slope adapted to the curved shape of the loop 20 so as to guide it.

1. An elastic connection terminal for an electric device, said device comprising a conducting part located at one end thereof and comprising a support strip having a front face and a back face comprising a connection region, the terminal for being fastened to the support strip and comprising:
 an elastic loop comprising a fitting arm, a cable clamping arm and a bent part connecting the fitting arm and the clamping arm, the fitting arm for abutting the front of a support strip of an electric device and being in contact with a conducting part of an electric device, said clamping arm having a window for clamping a cable between the back face of such support strip and an edge of the window; and  
 an auxiliary part for stopping one end of a cable inserted into the terminal, wherein  
 the auxiliary part is for being brought into contact with the back face of a support strip of an electric device and comprises at least one attachment element for gripping a region of such a support strip, thereby joining with such a conducting part of an electric device, and guide panels, the panels for extending to a connection region of a support strip of an electric device and comprising attachment elements located adjacent such a connection region, wherein  
 the guide panels each have an end portion having a profile for slidingly receiving the clamping arm.  
 
   
   
     2. The terminal according to  claim 1 , wherein the auxiliary part further comprises a back wall, wherein the guide panels are for abutting a support strip of an electrical device together with the back wall to define an individual compartment for an individual cable, each compartment being electrically isolated from an adjacent compartment. 
   
   
     3. The terminal according to  claim 1 , further comprising a protective part located in the elastic loop and for limiting bending of the elastic loop, the protective part being independent of the auxiliary part. 
   
   
     4. The terminal according to  claim 1 , wherein the auxiliary part comprises at least one stop for cooperating with a stop face of a housing of an electric device. 
   
   
     5. The terminal according to  claim 1 , wherein the auxiliary part comprises a bottom comprising an assembly tongue for limiting movement of said elastic loop, said tongue for passing through a slit of such a conducting part of an electric device to project on the front side of a support strip of such an electric device. 
   
   
     6. The terminal according to  claim 5 , wherein the tongue comprises a click-fit element for connecting the auxiliary part to a conducting part of an electric device.
